Understanding EDMA and McBSP

Started by xoni...@yahoo.es September 19, 2006
Hi all,

I`m newbie to DSPs and I`m using TMS320C6711DSK. I want to generate a serial signal, which has 80 bits at 1MHz every 250 uscs. I want to use timer1 to prompt the start of the signal, and McBSP with EDMA to generate the signal.

I'm able to make it once configuring the EDMA and McBSP properly, but I can't make it periodically, the EDMA interrupt is not generated. How can I do it?? Is it possible?

Thank you in advance!

Best regards,

Sonia
